To generate a short year return, review the steps below for the applicable module:
If I've already e-filed the 2023 tax return in Lacerte 2023, can I e-file a Short Year 2024 return from Lacerte 2023?
No, each year can only e-file one non-amended filing for each tax year. Since the 2023 tax return was e-filed, you would not be able to file the short year 2024 return from Lacerte 2023 as it would be the second return using the 2023 forms.
You will need to either paper file the 2024 return, or wait for the Lacerte 2024 program to be released with final forms, and e-file the 2024 return from Lacerte 2024.
